Boot manager problem with triple boot XP/Vista/Win7
Posted on 2009-07-08
On my system I could dual boot with EasyBCD into XP Pro and Vista Ultimate.
Now I wanted to add Windows 7 RC64bit to my system. I booted into XP, installed Partition Magic 8, made room on the far right end of my hard disk, made that partition bootable and set it to active(so fist 2 partitions are XP and Vista, then 2 partitions contain data and last partition is for Win7).
I was able to install Win7 with no problem.
Question: I want the boot manager to show XP, Vista and Win7. How? I need to able to delete Win7 (because I use RC version)
Problem: after installing win7 I didn't get the boot manager. Bcdedit shows only Win7. If I set the Vista partition to active I get the error: "windows failed to start" and "repair your computer" and "File: \BOOT\BCD
Info: An error occurred while attempting to read the boot configuration data"
When I set the XP partition to active I get my old boot manager with XP and Vista. I can boot into XP without a problem. If I boot into Vista I get the error: autochk program not found and then a BSoD with: Stop C000021a and 0xc000003a
